media: ti: cal: Clean up mbus formats uses

Clean up the CAL drivers uses of mbus formats:

- Switch all YUV formats from 2X8 formats to 1X16, as those are what
  should be used for CSI-2 bus.

- Drop 24 and 32 bit formats, as the driver doesn't support them (see
  cal_ctx_pix_proc_config()).

- Switch RGB565_2X8_LE to RGB565_1X16 (for the same reason as for the
  YUV formats) and drop RGB565_2X8_BE as it cannot be supported with
  CSI-2.
